摘要： The object of the invention is a foil fuse made on a circuit board, which fuse consists of a narrowed part (3) of a foil conductor (2) on the surface of the circuit board (1), and of a protective capsule (6, 7) covering the said part. To guide the hot gases and any splashes of molten material produced when a fuse blows to the safe side of the circuit board, there is a gap (4) in the circuit board (1), which is covered by the protective capsule (6, 7) and located adjacent to the foil fuse (3).

摘要： In an electrical fuse element (1), comprising a substrate (2) with contacts (11) arranged on two opposite sides of the same, between which contacts there runs a fusible conductor (3) which is produced in a laminating process and is connected electrically conductively to the contacts (11), the fusible conductor (3) is covered at least in the region in which the current-breaking operation proceeds by a pasty composition solidifying in a thermal process to form a mechanically stable layer (8), vitrifying in particular at least on one surface. Alternatively the covering of the fusible conductor (3) in the above-mentioned region is formed by a pasty composition which solidifies to a porous state and which for its part is covered by at least one further, mechanically stable layer and is closed from the outside.

摘要： An overvoltage protection circuit is provided for protecting electrical equipment from transients on power lines (41, 42). The circuit has a string of series-connected silicon avalanche diodes (SADs) (40) connected across the power lines (41, 42) to provide an initial clamping threshold before energy-absorbing modules (43a, 43b, 43c) come on line to provide secondary clamping. The modules (43a, 43b, 43c) include a number of metal oxide varistors (MOVs) (44) connected in parallel and a switching device in the form of a gas arrester (45) connected in series with the MOVs (44). A resistance (46) is connected in parallel with the gas arrester (45) to form a high pass filter with the natural capacitance of the MOVs (44). This maintains the voltage across the resistance (46) well below the switch operating level during normal conditions and enables a component such as a 230 V fast acting gas arrester (45) to be used. In an alternative embodiment, the gas arrester (45) may be replaced by a solid state swich, such as a Sidator or a Triac.

摘要： A fault current fusing resistor, comprising a substrate (13) on which there is a line (10) of resistive film formed of metal and glass in a conductive film, which line (10) is closely confined by containing and sealing substances (19, 22) to prevent venting of vapor from the line (10) during the fusing caused by an electrical fault condition.

摘要： This film resistor is formed of an alloy whose principal components are nickel and phosphorus. On the surface of an electrically insulating base made of ceramic or the like, a conductor is provided by etching, activating, and electroless plating in that order. Then an alloy film whose principal components are nickel and phosphorus is formed not by electroless plating, but by electroplating. By adapting electroplating, it is possible to make the alloy film thinner in the central part of the surface of the insulating base than the parts of the edges. If an overcurrent is applied, fusing starts preferably at this thin part.

摘要： A surface-mount fuse (2) for protecting a circuit, includes a substrate (4) and a metal strip (30) evenly attached to a surface (6) of the substrate with a layer of adhesive material (40). The metal strip (30) has two connection regions (32, 34). The fuse further includes two wire leads (50, 52) connected to the connection regions (32, 34). One alternative for the wire leads can include clip leads or other terminal leads. The fuse also includes a protective layer (70) disposed on the fuse link. A method of making the same is also disclosed.

摘要： A thin film surface-mount fuse (58) having two material subassemblies. The first subassembly includes a fusible link (42), its supporting substrate (13) and terminal pads (34, 36). The second subassembly includes a protective layer (56) which overlies the fusible link (42) so as to provide protection from impacts and oxidation. The protective layer (56) is preferably made of a polymeric material. The most preferred polymeric material is a polyurethane gel or paste. In addition, the most preferred supporting substrate is an FR-4 epoxy or a polyimide.
